To all whom it may concern: a

Be it known that l, HERMAN E. BAUM- GARTNER, a citizen; of-the United States, and

residing at Usagefin the county of Mitchell 4 and State of Iowa, have invented a new and useful Improvement in Apparatus for Cooling or Agitating Air, of which the followin is a specification.

' y invention relates to an apparatus for cooling or agitating air; and has for its object, a device of this class to be used. in connection with a fan or the like, and so die-- signed as to cause a current of airto pass through a restricted area at the back of the fan, thence through the fan from. where it is circulated.

A further object of my'invention is to provide a device of this class with means for preventing the fan from drawing warm air into the current produced, until such current has passed the fan.

A further object of my invention isto provide a device of this class .of simple, durable, eilicient and inexpensive construction.

The above and other features of novelty, advantages and capabilities of my invention, will become apparent from a detailed description of the accompanying drawings, in which Figure l is a perspective view of an ap paratus embodying my invention; and 2 is a central sectional view of the same, showing a column of ice and fan in place Generally stated, my invention consists or a receptacle for holding a column. of ice, to which receptacle is secured a vertical shield provided with" a central opening of a relatively large diameter, which apparatus when in use is placed at the back of, and adjacent to, a suitable fan, the shield being in a plane at right angles to the axes of the fan. The receptacle is provided with a column of ice and by operating the fan, a current is produced which draws the air over the column of ice, thence through the opening in the shield, thence outwardly past the fan from where it is circulated Referring to the accompanying drawings I in detail, l have used the reference numeral till 10, to designate the ice receptacle as a whole. This receptacle consists of an upper and lower compartment, the lower end of the upper compartment being seated within the upper end of the lower compartment, as best shown in Fig. 2. However, 1 do not wish to limit myself to this particular reprovided with a central opening,

ceptacle, as any suitable receptacle may be used. The upper part 11, is provided with adished shaped bottom 12, which bottom is through which opening the water passes into the lower compartment as the ice l7, melts. If desired, the lower compartment can, of course, be connected with a suitable drain, and thereby eliminate the necessity of emptying this receptacle from time to time, as would otherwise be necessary.

Secured to the upper compartment 11, of the receptacle 10, is a vertical shield 13, which is provided with a central opening of a relatively large diameter, as best shown in Fig. 1. The shield 13, may be placed adjacent to the receptacle 10, without in any way being connected, but I prefer that it be attached thereto by any suitable means, such as a rivet or bolt. The diameter of the opening in the shield 13, is less than the diameter of the perimeter of the fan, as otherwise the fan blades 18, being larger at their outer ends, than at their center, they would draw warm air, which would increase the temperature of the cool current, and also have a tendency to upset such a current. By providing a shield with such an opening, it also causes the fan to draw the air at a greater velocity over the ice in a smaller space, and thus more rapidly cools the air.

Securedto the shield 13, by any suitable means, is an arch shaped member 15, which' serves as a housing for the fan 16. This not only eliminates the danger of one coming in contact with the fan, but also protects to a very great extent the cool current from being interrupted, or its temperature increased by the warm air, until after the cool current has passed the front of the fan, and also facilitates the velocity of the current as by having the housing 15, attached to the shield 13, it makes it necessary that all the air producing the cool current should be drawn through the central opening in the shield 13. I

The fan 16, may be of any suitable con struction of a convenient size and form, and may be driven by an electric current or any other convenient motive power, or any other suitable means may be used for producing a current, drawing the air over the ice in the receptacle l0, and through the opening in the shield 13, as indicated by the arrows in Fig. 2.
